So these are my steps in making a spiral staircase. I started with a circle divided up with another circle that i pulled up in the middle. The hardest part was figuring out how to make the other level. But i figured out that I just had to bring the post down in the middle and put another circle on that and then start the whole process over. It became easier as I went on because you just have to repeat everything every time you start a new level. I deleted the blocks of the different sections that I pulled up to make it look more like a spiral staircase. It's a pretty simple project so people could make them to put into houses they have made!
